I've recently upgraded my computer from a duo core dual cores only, gt 8800, and 2.5 GB RAM, to gtx 780, i7-4770k, and 16 GB RAM 1600mhz (I had a laptop but I did the rendering on the old desktop, because my laptop overheats). So... When I installed c4d on my new desktop, I can't see that much difference in the speeds of the rendering process, does anyone have any idea in making it faster? And will a workstation gpu increase the speed of the render, I also heard that cinema 4d uses cpu rendering but, can you explain to me in detail of what I'll have to do in order to run a GPU rendered? Thanks for who-ever that will try to help me.
